Name three environmental factors that can damage the genes that produce those enzymes

1. UV rays.

2.  X-rays.

3. Chemical agents. Example Ethidium bromide.

Explanation:

Three environmental factors that can damage the genes that produce those enzymes include UV rays, X-rays and chemical agents. These agents are called mutagens. When an organism is exposed to these agents, they alter the cells DNA resulting to changes in the genetic makeup of the organism and in turn affect the production of enzymes. Enzymes are proteins, and once the DNA is affected, their production is inhibited. In most cases, mutated DNA  produces enzymes with poor or abnormal function.
